ro ALL WHoM Ir MAY CONCERNS.

Be-it known that I, GARDNER WATERS, of Cincinnati, inthe county of-Hamilton, and infth'e State ofV Ohio i have invented certain new and useful Improvements in #Automatic Lubricators g and I do hereby declare that the following is a full, clear, and exact description there.i`,'l reference being had to/'the accompanying drawings, forming a part of this specification.r

y Figure l is a vertical section, showing thefor-mation of my improved lubricator.

.-Figure 2 is a similar 4section,'showing the modeof casting the guard upon and within the opening of the reservoir.

cast around and within the opening inthel'ower part of the reservoir, as hereinafter shown.

In the drawings, A represents a glass Vreservoir','oi` 'a form nearly spheroidal, but slightly ovoid by. prefer` ence, having a single opening at Vits lowerv and` smaller portion. This opening should be, after the tube and guard are attached, about one-fourth ofY an inch in diameter, so .as to admit of being easily iilled by'pouring in through the opening, and yet so smalll as to forbid theescape of the oil. by its own gravity when the'reservoir' is inverted.

My inventionprincipally consists in providing an automatic lubrieator with a guardoiz easily-fused metal, l

B is the discharge-tube, formed ofa single piece ofl metal, and perforated by drilling, so as to forma tube .of two diameters, a IJ. Near `the upperend of this tube is formed a square hexagonal shoulder,rso as to make 'it easy to turn the tube tightly into the desired journa1box.. e, elasting packing, between bottom of guard -D and shoulder of tube B. v v

l C is a small brass tube, tapped on the inside, to correspond with the screw on the outside of'the upper end of tube B, and (in figs. 1 and 2) is secured in the opening of the reservoir bymeanslo-f the guard D.

D Yis what I term the guardff for protecting and strengthening the opening in the reservoir, and'f-'or receiving the tube B, or for'securing the hard-metaltube Q, which receives the tube B. Itrwill be seen that this guard `D g's. 1 and 2, surrounds the' outsideloif Ythe lower .portion of reservoir, and at the same time extends up in cylindrical form through the opening, and then expands in button-form-within. the reservoir, 'so as to be most closely attached to and both internally and externallysurround the opening of the'reservoir, thus thoroughly protecting the saine. YIt will be well to describe-onemode ofV making the 'guard D in this form which I have satisfactorily practised. i A Y l .In g. 2,'X represents a solid metallic mould, conforming to they desired exterior shape of the guard D..4 l.Y is a metallic tubular core, whichl iitstightly (but not too tightly) in the centre of the mould. Theopening-o-iu the core is for the necessary escape of air. The` mould and its corerbeing in place, as shown in g. 2, the tube C is then slipped down over the core, resting on the bottom of the mould, as shown. The mould the reserf v oir are then heated. The mould is thon' filled with some suitable easily-fusedmctal, Y(such as common solder.) The reservoir is then quickly and centrally put over the eoreand forced down to the bottornof the mould, thus displacing a portion of the"motal .,iarid forcing it up into the reservoir through the annular space betwcenthe tube C .and sides of the opening in the reservoir, thus forming the guard, as shown in the drawing.`

' Although I prefer using the tube of hard metal, I may dispense with it by'm'aking the guard. itself of some easilyusible hard alloy.

Having thus fully described my said. invention, I desire to have it understood Ythat I do not claim, in thispatent, forming the socket or guard upon and around the stem of. thebulb, by casting solder or'other fusible metal,.nor do I claim casting within the'lcylindrical portion of the necksuch solder or fusible metalbut What I claim, isg n p I Anautomatic lubricator, the glass bulb of which is provided with a soft-mctal socket or guard, cast not only around but also within'the lower portion of said bulb orreservoii-,sothat the metal shall form a button against` the enlarged or bulging part of the reservoir, substantially as and for the purposes herein set forth.`

In testimony that I claim the above-'described invention I have hereunto signed my name, this V27th day of'.`
